Great, quartz glass cleaning and maintenance can do this

        Quartz glass is an amorphous material with a single component of silica. Its microstructure is a simple network composed of silica tetrahedral structural units. Due to the large chemical bond energy of Si-O and the tight structure, optical quartz Glass has unique properties, especially the optical properties of transparent quartz glass are very good, and it has excellent transmittance in the continuous wavelength range of ultraviolet to infrared radiation.

        Quartz glass has extremely low coefficient of thermal expansion, high temperature resistance, excellent chemical stability, excellent electrical insulation, low and stable ultrasonic delay performance, excellent UV spectral performance and visible light and near-infrared spectral transmission. performance, and has higher mechanical properties than ordinary glass.

Quartz glass is an acidic material. Except for hydrofluoric acid and hot phosphoric acid, it is inert to any other acid and is a good acid-resistant material. The degree of corrosion of quartz glass by alkalis and salts at room temperature is also extremely small, so the use of quartz glass in these reagents is not excluded. Quartz glass has the characteristics of non-hygroscopic and non-weathering. It is very sensitive to all alkali or alkaline earth compounds, which in small amounts can induce crystallization of quartz glass at high temperatures.

        Therefore, in the cleaning and maintenance of quartz glass, we should pay attention to the following points:

        1. Quartz glass products are very valuable, so we must be very careful when using them, and must be handled with care;

        2. If the quartz glass needs to be used in high temperature, we must wipe it clean before use. It can be soaked in a 10% hydrofluoric acid solution, then cleaned with high-purity water or treated with alcohol. Thin-line gloves should be worn during operation to avoid direct contact with quartz glass with hands;

        3. Different quartz glass products have different high use temperatures, we cannot exceed this temperature when using, otherwise it will cause crystallization or softening and deformation of the product;

        4. Quartz glass is an acidic material, so when it is used at high temperature, it must avoid contact with alkaline substances (such as asbestos, water glass and potassium-sodium compounds), otherwise it will greatly reduce its anti-crystallization performance. ;

        5. Although the quartz glass material has extremely high thermal stability, it can withstand sudden changes in temperature difference. However, in actual use, due to the difference in residual strain and product shape, there are corresponding differences in thermal stability, so attention should be paid during use.
